Swift vs Kotlin

Swift-Kotlin

What is Swift?

Swift is a multi-paradigm, compiled programming language invented by Apple for its own operating systems to make it easy for the Apple devices. iOS, iPadOS, tvOS, Apple smart wears operating system and every other device. In short, Swift is a language for developing all the applications on all the Apple devices. Swift was inspired by Objective-C, C#. Swift was mainly developed to work with Apple’s Cocoa and Cocoa Touch. Swift has amazing features to address common but problematic programming errors smoothly. Swift can be executed with C, C++ and Objective-C in the same program. Swift is the best language for mobile app development for iOS.

What is Kotlin?

Kotlin was developed by JetBrains and Google. Kotlin is a cross-platform, statically-typed general-purpose language with type interface. Kotlin is mainly focused on mobile app development but it can also be used for web app development instead of JavaScript. Main reason t develop Kotlin was to have a language that’ll be interoperable with Java and the JVM version of its standard library. Kotlin is inspired by C#, Groovy, Java and Python.

The big question- Swift vs Kotlin

Purpose of Development

Swift was built for iPhone app development, whereas Kotlin was for android app development.  Apart from, the purpose of development they both have very different syntax and features for mobile app development. 

Difference in the Language Norms

Swift

  • Swift “Enums” are more effectual.
  • Swift uses no data class.
  • Swift does not support delegated classes or delegated properties.
  • Swift has no provision for annotations.

Kotlin

  • All Kotlin classes are “final” by default, the developer has to use specifier as er the need.
  • Kotlin does not support struct or passing data by value.
  • Kotlin uses no tuples.
  • Kotlin doesn’t support typealias.
  • Kotlin doesn’t have guard statement.

Memory Management

Swift uses ARC or Automatic Reference Counting for memory management. Kotlin uses Garbage Collection memory management approach.

Interoperability

Kotlin code is interoperable with Java, the sole reason to develop Kotlin is to have an interoperable language with Java. Java and Kotlin classes can be in the same file and the application will run smoothly. Likewise, Swift coexist with Objective-C code.

Wrapping UP

Let summarize what we have learnt so far, Kotlin is a programming language for used Android app development whereas Swift is used for iPhone application development. Both Kotlin and Swift are built on top of the modern programming approach and software design pattern. Both the languages provide several inbuilt functions defined in an extensive list of libraries and amazing features to the mobile app development companies. Like always there are both the similarities and differences between the two languages. Both Kotlin and Swift are evolving to in term of the performance, programming advancement and security. As both, the languages have their own perks but they both are great in their own ways like Kotlin for Android and Swift for iOS.
